PyGMC is a Python library for interfacing with the GQ Electronics GMC 500, 500+, 600, and 600+ Geiger-Muller Counters using the device's custom protocol. It implements all documented commands and provides an easy-to-use interface for accessing and updating the device configuration.

pip install pygmc

from pygmc import GMCConnection, GMCGeigerCounter

# Establish a connection
connection = GMCConnection(port='COM4')

# Create a Geiger counter instance
geiger = GMCGeigerCounter(connection=connection)

# Fetch the current CPM (Counts Per Minute)
cpm = geiger.get_CPM()

# Print the CPM
print(cpm)

Detailed documentation for each method is provided in the source code itself. The following are a few key methods and what they do:

• GMCGeigerCounter.get_CPM(): Fetches the current CPM (Counts Per Minute) from the device.
• GMCGeigerCounter.get_battery_voltage(): Fetches the battery voltage from the device.
• GMCGeigerCounter.get_config(): Fetches the current device configuration.
• GMCGeigerCounter.set_config(config): Sets the device configuration. The config parameter should be a dictionary matching the structure defined in the config_format constant.
• GMCGeigerCounter.reboot(): Reboots the device.
• GMCGeigerCounter.factory_reset(): Resets the device to factory settings.

You can find the complete list of methods and their description in the GMCGeigerCounter class in the code.
